Innovative alloys, like the new tungsten-copper material developed by Sirui New Materials, are emerging to address the intense heat in 400G+ modules. These modules are essential for converting electrical signals into light signals and vice versa, forming the backbone of fiber optic communication systems in data centers. Our molybdenum-copper composites are most suitable for IGBT power modules and modern GaN or SiC MOSFET power transistors used in inverters of electric cars. The thermal properties of our molybdenum-copper laminates (CMC) can be customized for specific requirements of high-frequency electronics such. Heatspreaders for Opto electronics, Wireless communication, LED substrates Cu-W is a combination of Tungsten (W) which has low thermal expansion, and Copper (Cu) which has high thermal conductivity. The thermal expansion can be adjusted to surrounding materials such as Alumina and Kovar. Also, with. Contrary to injection molding technology, Spectra-Mat's unique technology to infiltrate copper in an highly homogeneous sintered tungsten matrix guarantees the homogeneity of thermal conductivity of the tungsten copper submounts along the three axes, a very important requirement for multi diodes. For the first time, here we report the assembly of a pyridine-protected tungsten–copper cluster on porous alumina, and find superior optical limiting (OL) properties retainable for multilevel clustering due to unaffected reverse saturable absorption (RSA) and constant photo-excited triplet states.
